APPENDIX E: INFORMATION ON 4-20 MA ANALOG OUTPUT

GENERAL INFORMATION

Some models provide a passive analog 4-20 mA output on two terminals. These terminals
are covered in Chapter 2 (see Section 2.2.5).

The output tracks the weight displayed on the indicator, so you must first have the indicator
configured and calibrated correctly in order for it to work properly.

Here is a working connection diagram used at the factory to test:

24 VDC

R = 250 ohms

4-20A or AA

4-20B or BB

NOTE 1

: In your application, substitute the actual input device for R

. If your input device is

polarized, connect the common lead to the negative lead of the 24 VDC power supply and
the positive lead to the BB wire.

NOTE 2

: The 4-20A (AA) and 4-20B (BB) wires are not polarized. You may connect them in

any manner you wish.

Here is a suggested connection diagram for a PLC:

+24 VDC

or AA

or BB

TI-500

PLC

GND

4-20A

4-20B

NOTE 1

: Do NOT connect the indicator ground to the PLC ground.
